Patent CA-2122880-C (CA)
Title: Crossbar switch for multi-processor system
Inventor: SHARMA VINOD
IPC: G06F15/16
Filed: 1994-05-04
Granted: 1999-07-27
Abstract: A self-routing crossbar switch interconnects a plurality of processors with a plurality of memory modules.          In a self-routing crossbar switch connecting N processors and N memory modules, a processor is connected to each input port and a memory module is connected to each output port; each of the N processors can transmit a memory request simultaneously provided that there is no port contention and no bank contention.  Port contention occurs if two or more processors attempt to access the same output port of the self-routing crossbar switch at the same time.  The memory module consists of several memory banks that are connected in an interleaved manner.  If the memory bank is accessed before it is ready to accept a new request, bank contention is said to have occurred.  In the self-routing crossbar switch the requests directed to a port are first passed through an aligner and a conflict resolution logic.  There is one aligner associated with each output port.  The aligner inputs the requests directed at an output port and aligns them so that, at the output of the aligner, all the active requests appear in a consecutive fashion.  The conflict resolution logic resolves the port and bank contention.

IPC: F04B1/14
Filed: 1994-06-07
Granted: 1999-03-02
Abstract: A double-headed tupe compressor has a disk plate.  The disk plate is rotatably supported on a drive shaft for driving each piston along a reciprocating path.  The plate is curved in a single direction to form a solid cam on its surface.  The cam transforms  a  single  rotation  of  the  plate  into  two reciprocating movements of the piston. Cam followers provided between the plate and the piston are formed to be comformable to the cam.  The cam followers contact and roll on the piston, and slide on the cam.

Title: Symmetrical multi-layer metal logic array with continuous substrate taps and extension portions for increased gate density
Inventor: YIN PATRICK
IPC: H01L21/82
Filed: 1994-06-22
Granted: 1998-12-22
Abstract: A  gate  array  architecture  is  disclosed  that  utilizes significantly less silicon area than the prior art.  The core cell includes a four transistor arrangement in which a substrate tap is located adjacent to the transistor pair.  This provides for a more "symmetric" cell array than those in the prior art.  Through the placement of the taps outside of the transistors the power line connections can be routed in a simple and efficient manner.  The architecture includes an extension portion in the contact region of the cell to further reduce wiring complexity.  In addition the gate array architecture mirrors pairs of transistor columns to allow for the sharing of substrate taps between pairs of columns.   This mirroring feature further reduces routing complexity.

Abstract: A channel dropping filter includes three frequency routing devices, one which functions as an input device and two which function as output devices. The first frequency routing device has one input for receiving the input signal and at least N outputs, where N corresponds to the number of frequencies that compose the input signal. The N outputs of the first frequency routing device are each coupled to an optical switch. Each optical switch has a first output coupled in consecutive order to one of the N inputs of the first output frequency routing device and a second output coupled in consecutive order to one of the N inputs of the second output frequency routing device. A controller is employed to selectively switch the optical switches between first and second states for directing each optical frequency component demultiplexed by the firstfrequency routing device to the first and second output frequency routing device, respectively.

Abstract: A valve body is formed in two half sections which are secured together to define a drain line passage and to confine therebetween a thin gate valve blade for movement between a lower open position and an upper closed position.  A cylindrical bellows is sealed to the valve body above the passage and is covered by circular top plate which is connected by a rod to the valve blade.  The bellows defines an expandable fluid chamber connected by a bottom port to the drain line passage.  The valve body is connected within a sewage drain line extending under a floor. In the event sewage water backs up within the drain line, air within the bellows is compressed to expand the bellows upwardly for closing the valve.   When the sewage water drains from the drain line,  the air pressure reduces, and the bellows collapses due to the weight of the top cover plate and automatically returns the valve blade downwardly to its open position.

They also retrieve stored video messages via the LAN or WAN from the messaging system and play them to users. The messaging system stores both video and non-video messages and has a telephony user interface (114-115 and 118) for storing and retrieving non-video messages and for accessing non-video portions of all messages. The video terminals perform functions, such as answering of video calls and recording of video messages, on behalf of the telephony messaging system which cannot itself perform those functions, while the messaging system performs functions, such as providing a rich set of messaging features and providing telephony access from a variety of different telephony terminals to at least portions of the video messages, on behalf of the video terminals which cannot themselves perform those functions.

Abstract: A harvester (10) which uses a rotary style cutter bed (30) has a series of rotary cutters (32a-32j) extending across the path of travel of the machine and rotatable about individual upright axis. Part of the cutter bed (30) is a flat gear case (34) containing a train of intermeshed spur gears (35) that serve to distribute power between the cutters above the gear train. Each end of the gear case (34) has a hollow, gearless extension welded thereto which supports at least one additional outboard cutter that receives its driving power exteriorally of the gear case (34). One embodiment uses a mechanical drive to bring power to the upright shaft of the cutter having the first spur gear so that the cutters with gears receive all their power from the driven cutter. The outboard cutters not having gears are driven by exterior, over-the-top drive mechanism coupled with the shafts of the first and last geared cutters, such drive mechanism alternatively taking the form of timing belts (120).

Title: Voiceband signal classifier
Inventor: SEWALL JEREMY S
IPC: H04M11/06
Filed: 1997-01-03
Granted: 2002-08-13
Abstract: A method and apparatus for classifying signals into a multiplicity of signal classes which employs discriminant functions of low-complexity discriminant variables that are computed directly from the passbanb signal. One possible discriminant variable is the central second-order moment, normalized with respect to signal power, of the result of applying a nonlinear operation, such as rectification, to the passband signal being classified. Other possible discriminant variables are the lags of the autocorrelation sequence of the passband signal, normalized with respect to the signal power. The discriminant functions can be linear or quadratic functions of the discriminant variables. The accuracy of the classification functions is maximized by employing discriminant functions that are selected to minimize, in a statistical sense, the probability of making erroneous classification decisions. The method can be applied to the problem of classifying voiceband data (VBD), facsimile (FAX), native binary data, and speech on a 64 Kbps digital channel. The method may be implemented using exclusively linear or exclusively quadratic discriminant functions of the discriminant variables. Hybrid two-stage systems may be employed to reduce the computational requirements at the cost of an acceptable loss in classification accuracy with respect to a classifier that uses only purely quadratic discriminants functions. In such a hybrid system the first stage employs linear discriminant functions to make classification decisions into a smaller number of possible preliminary signal classes. The decisions of the first stage are then refined by a second stage that uses nonlinear discriminant functions such as quadratic or pseudo-quadratic functions. The second stage of a hybrid classifier then assigns the signal into a larger number of possible classes than does the first stage of the classifier alone.
